Dr Kelvin Kemm: Evidence of sunspot involvement in climate change too compelling to be brushed aside
The sun was also very quiet in 1913, so runs of 200-plus spotless days are rare, but not that rare. As I have already said, the global warming and cooling issue is complex, and so a run of 200-plus days without sunspots cannot be compared to a 50-year quiet period during the Little Ice Age, but it is cause for some scientific thinking.
Further, a cooling that could be initiated by a lack of sunspots will induce other climatic effects that will either favour warming or cooling. The jury is still out on exactly what happens, but the evidence for sunspot involvement in climate change is just too compelling for it to be brushed aside by those who want to cling to the simplistic idea that man-made CO2 is the only factor.

As I understand it, the hypothesis of the Danish National Space Center goes as follows:
Active sun → enhanced magnetic and thermal flux = solar wind → geomagnetic shield response → less low-level clouds → less albedo (less heat reflected) → warmer climate
Quiet sun → reduced magnetic and thermal flux = reduced solar wind → geomagnetic shield drops → galactic cosmic ray flux → more low-level clouds and more snow → more albedo effect (more heat reflected) → colder climate
That is how the bulk of climate change might work, coupled with (modulated by) sunspot peak frequency there are cycles of global warming and cooling like waves in the ocean. When the waves are closely spaced, the planets warm; when the waves are spaced farther apart, the planets cool.
